    Abstract: Provided is a method and apparatus for encoding/decoding a multi-channel audio signal. The apparatus for encoding a multi-channel audio signal includes a frame converter for converting the multi-channel audio signal into a framed audio signal; means for downmixing the framed audio signal; means for encoding the downmixed audio signal; a source location information estimator for estimating source location information from the framed multi-channel audio signal; means for quantizing the estimated source location information; and means for multiplexing the encoded audio signal and the quantized source location information, to generate an encoded multi-channel audio signal.

    Abstract translation: 提供了一种用于编码/解码多声道音频信号的方法和设备。 用于编码多声道音频信号的设备包括：帧转换器，用于将多声道音频信号转换为成帧音频信号; 用于对混淆的音频信号进行缩混的装置; 用于对缩混后的音频信号进行编码的装置; 源位置信息估计器，用于从成帧的多声道音频信号估计源位置信息; 用于量化估计的源位置信息的装置; 以及用于多路复用编码的音频信号和量化的源位置信息以生成编码的多声道音频信号的装置。
